To all whom z'tmay concern.'

Be it known that I, HARRY M. PFLAGER, a citizen `of the United States, residing at St, Louis, Missouri, have invented a certain new and useful Improvement in Booster- Motor Supports, of which the following is a full, clear, and exact description, such. as will enable others skilled in the art to'which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

M invention relates generally totrailer truclisfor locomotives and more specifically to a trailer `truck which is provided with a supporting frame designed particularly to receive a booster motor for locomotives Such as disclosed in United States patent to Howard L., Ingersoll, No. 1,339,395, dated May 11, 1920.

In my Patent No.` 1,357,928, dated November 2, 1920,' I have disclosed a form of mounting for locomotive booster motors such as` contemplated b the Ingersoll sys tem, and in my Patent o. 1,381,496, dated Julie 14, 1921, I have `discloseda -form of trailer truck also especially designed for use in connection with the Ingersoll system.` I

I doI not,'therefore, claim in this application any of the inventions set forth in the claims of the before-mentioned atents.

The principal object o my present invention is to provide a relativelysimple, strong and efficient supporting frame or bed plate which will readily cooperate with the trailer truck framein supporting thebooster moi tor, its associated parts; and the driving con`- Vnections between said motor and the trailer truck i axle( Q Further objects of my invention are, to

construct the supporting frame or bed plate,

in a single piece, preferably hy casting, thereby materially increasing the strength and rigidity of the `complete structure and eliminating the time, labor andexpense ordinarily involved Vin the assembling of a built-np structure, and, further, to form integral With the hed` plate or` supporting booster motor.

y Iieferring by numerals to the accompanyingdrawings, embodiment of my invention, lOdesig'nates a radial trailer truck frame, the rear por` tions oi the sidel members oi' ,which are ,arched and provided with pedestal jaws be tween which l.are arranged in the usual manner the journal boxes which receive the ends of the trailer truck ,axle 11,.and the latter being provided with the usualwheels 12'.

It will be nnderstoodl that this trailer truck is pivot'ally connectedfalt." its forward end tothe locomotive frame and for a de- Which illustrate a practical ,A

tailed description of the constructionot this frame, reference may he hadv tomy aforesaid Patent, No. 1,381,496.

The rear transverse rail 13 of the trailer truck frame is provided at a centralpoint Y .l

ing flanges 17.` Formed integral-with this y plate at or adjacent to its rear end is a transversely disposed depending flange v18, the end portions of which are extended upward on the outer faces of the as designatedby 19.

Formed o n the underside oi the plate 16. a `short distance in front of its rear end and at a pointmidway between `its sides is a side edges 17 horizontally` disposedportion 20` having` a secured in any suitable manner on top of flat underface and which latter bears directly on to of the bearing member 15. Passlng vertically through the allned apertures formed in the transverse rear member 13 of the truck frame bearing plate 14 and bearing members 15 and 2Q 1s a pin or `bolt 21 which retains the parts just men.

'lheforward portion of theplate 16 is bifurcated, thereby forming forwardly pro` jecting portions 22 and the forward ends of lsaid forwardly projecting portions terminate in transversely disposed semi-cylindrlcal bearings 23-which receive the trailer truck axle l1 the latter being retained in said 4bearings by bearing membersV 24 which are arranged beneath and secured to sald bearings 23 in any suitable manner.

Thus it`will be seen that the bed plate has three bearings or points of support upon the trailer truck, namely, two upon the trailer truck axle 11,'and one upon the rear member 13 of the trailer truck frame.

. Formed on the vforwardly projecting p0rtions 22 of the bed plate and a slight distance to the rear of axle'bearings 23 are 30 transversely alined, bearings 25 which receive the crank shaft 26 of the booster motor and the latter beingmaintained in said bearings by suitable removable cap plates 27.

formed integral with the bed late 16 and 4connections between the booster motor and trailer truck axle 11 and which connections 'are fully described in said before-mentioned Ingersoll atent.

he lcylmders A of the booster motor are the rear portion of the ybed Aplate 16and arparts. Further, by forming the bed plate j.

ranged between said cylinders-is the steam chest B. Y r

The piston rods of the motor are connected in the usual manner to the crank shaft 26 and the driving pinion, C on the latter adapted to engage a gear lwheel D that is fixed on the trailer truck axle 11 between the bearings 23. I

Thus it will be seen that I have provided a relatively simple and eiioient bed plate Afor the booster motors'of locomotives, said bed plate being designed and constructed so as to readily coperate with the trailer truck in providing a firm and substantial support for the booster motor and associated in a single piece, the manufacturing `cost thereof'is minimizedand the finished struc.

frame ture while relatively light in weight has great strength and rigidity, and is provided at the proper poi-nts with integrally formed bearing members, brackets, and the like,

which receive essential motor mechanism.

It will be readily understood that minor changes inthe size, form and construction of the various parts of my improved bed plate or support for booster motors may be made and substituted for those herein shown parts of the booster and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim: l. The` combination with a radially movable trailer truck frame and its axle, of a booster motor bed plate formed in a single piece and provided adjacent to its forward ends with bearings' adapted to receive the trailer truckA .axle and the rear portion of said bed plate having bearing on said trailer truck frame.

l 2. A booster motorbed plate formed in a single piece and` provided adjacent to its forward ends -with bearings adapted to receive the axle of the trailer truck with which the bed plate,is associated, and the underside of said bed' plate being provided with a bearing that is adapted to engage a part of the frame of the trailer truck.

3. The combination with a trailer truck frame, 'of a booster motor bed plate sup ported by said frame and flexibly connected to the axle of the trailer truck and booster motor carried by saidbed plate, and bearings on sail bed plete for the crank shaft 0f said booster rnotol".

4. A booster motor bed plate formed in a single piece, bcaringsl on said bedplate, which bearings are adapted to receive the axle of the trailer truck with which the bed plate is associated, and bearings on said bed plate for the crank shaft of the supported Ooster motor.

5*. A booster motor bed plate formed in a single piece, bearings on said bed plate, .which bearings `are adapted to, receive the axle of the trailer truck with which the bed plate is associated, bearingson said bed platev for thel crank shaft of the supported oostermotor, anda bearing4 on the underside of. said bed plate, which last mentioned bearing is adapted to engage a part of the frame of the trailertruck.

projectinglforwardly from said plate, trailer truck axle bearings on said arms and booster motor crank shaft bearings on said adjacent to the trailer truck axle bearings.

7. A booster motor support `comprising a `horizontally disposed plate `adapted to be portion of a trailer 180 positioned on the rear Plate `truck frame, arms projecting forwardl from said plate, tmiler truck; axle bearings from said plate, and booster motor cran on said arms, and booster motor crank shaft shaft bearings on said arms. bearings on said arms. 10 8.
